TECHNICAL FIELD

The present application relates to the field of display technologies, inparticular to a display panel and a display device.

BACKGROUND

With the rapid development of display technologies, display panels anddisplay devices including the display panels are widely used. A displayregion of an existing display panel is provided with a plurality oftypes of signal lines, and a non-display region of the existing displaypanel is provided with a driver chip. All signal lines are electricallyconnected to respective signal terminals of the driver chip throughrespective connection lines on the non-display region so as to applyrespective signals to the respective signal lines through the signalterminals, thereby realizing display function, touch function andpressure-sensing function and so on.

Since a width of a region occupied by the signal lines is larger than awidth of the driver chip, and the connection lines are electricallyinsulated from each other (that is, a gap is present between any twoadjacent connection lines of the connection lines). As a result, theconnection lines are configured to be bent relative to the signal lines(that is, the connection lines take form of folded lines relative to thesignal lines) such that the signal lines can be electrically connectedto respective signal terminals of the driver chip. A large number of thesignal lines also cause a large number of the connection lines. Ingeneral, the driver chip has a relative small width, so that it isnecessary to elongate the length of the connection lines to realize theelectrical insulation between the connection lines in the case of thelarge number of the connection lines.

Since the same type of signal terminals on the driver chip correspondingto the same type of signal lines are adjacent to each other, the sametype of connection lines corresponding to the same type of signal linesare also adjacent to each other. As a result, a region occupied by thesame type of connection lines has a relatively small width. Therefore,this electrical insulation between the connection lines can only berealized by elongating the length of the connection lines, so that theregion occupied by the connection lines becomes large. Further, sincethe connection lines are arranged in the non-display region of thedisplay panel, this causes a large length of the non-display region. Inother words, large-sized frames of the display panel and of the displaydevice including the display panel are caused.

SUMMARY

Embodiments provide a display panel and a display device with narrowbezel, to solve the problem in the related art that the frame of thedisplay panel and the display device has a relatively large size.

Embodiments employ the following technical solution.

In a first aspect, an embodiment provides a display panel. The displaypanel includes touch lines each extending in a first direction; datasignal lines each extending in the first direction; touch connectionlines, display connection lines; and a driver chip having a plurality oftouch signal terminals and a plurality of display signal terminals. Thetouch signal terminals and the display signal terminals are arranged inone or more rows with one of the one or more rows having n touch signalterminals and m display signal terminals, the one or more rows extend ina second direction. Two adjacent ones of the n touch signal terminals inthe one row are spaced apart by one or more of the m display signalterminals, and where n and m are positive integers.

In a second aspect, an embodiment provides a display device, whichincludes a display panel provided according the first aspect.

According to the display panel and the display device provided in theembodiments, at least two types of signal terminals are provided on thedrive chip. The at least two types of signal terminals are electricallyconnected to the at least two types of signal lines throughcorresponding types of the connection lines, respectively. At least apart of a first type of signal terminals and at least a part of a secondtype of signal terminals are alternately and separately arranged, suchthat at least a part of signal terminals from the same type of signalterminals are not adjacent to each other. As a result, a distancebetween two edge signal terminals located at both ends of the same typeof signal terminals is increased. When a type of signal lines areelectrically connected to a type of signal terminals through a type ofconnection lines, since the distance between two edge signal terminalslocated at both ends of the same type of signal terminals is increased,a dimension of a region prepared for the same type of connection lines(i.e. a direction perpendicular to the connection line between the twoedge signal terminals) is increased in a lateral direction. Hence, it isnot necessary for a long length of the connection line in order torealize the electrical insulation between the connection lines, i.e. thelength of the connection line is reduced. Since the length of theconnection line is reduced, the dimension of the non-display regionoccupied by the connection lines (i.e. a direction parallel to theconnection line between the two edge signal terminals) is decreased in alongitudinal direction, hence decreasing the dimension of thenon-display region in the longitudinal direction, that is, decreasingthe size of the frame of the display panel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be described below in detail in conjunctionwith the accompanying drawings and specific embodiments. It isappreciated that the specific embodiments described herein are only usedfor explaining the present disclosure, but not limiting the presentinvention. Also, for the convenience of description, the accompanyingdrawings illustrate only the relevant parts of the present invention notall contents thereof.

An embodiment provides a display panel.

FIG. 1A is a top schematic view showing the structure of a display panelaccording to an embodiment. As shown in FIG. 1A, the display panelincludes at least two types of signal lines 11, at least two types ofconnection lines 12 and a driver chip 13.

At least two types of signal terminals 14 are provided on the driverchip 13, and the at least two types of signal terminals 14 areelectrically connected to the at least two types of signal lines 11through corresponding types of the connection lines 12, respectively. Atleast a part of a first type of signal terminals and at least a part ofa second type of signal terminals are alternately and separatelyarranged.

According to the display panel provided in the embodiment, in the atleast two types of signal terminals 14 disposed on the driver chip 13,at least a part of a first type of signal terminals and at least a partof a second type of signal terminals are alternately and separatelyarranged, such that at least a part of signal terminals 14 from the sametype of signal terminals 14 are no longer adjacent to each other (thatis, a type of signal terminals 14 are arranged to be separated byanother type of signal terminals). Since the space between adjacentsignal terminals is identical, in the display panel provided in theembodiment, a type of signal terminals 14 are arranged to be separatedby another type of signal terminals 14, so that a distance between twoedge signal terminals 14 (that is, the first and the last signalterminals 14) from the same type of signal terminals 14 (i.e. indicatedby A direction as shown in FIG. 1A) is increased in a lateral direction,as compared with the technical solution in the related art that thesignal terminals from the same type of are adjacent to each other. Whena type of signal lines 11 are electrically connected to a type of signalterminals 14 through a type of connection lines 12, since the distancebetween two adjacent signal terminals of the type of signal terminals 14is increased, a dimension of a region prepared for the type ofconnection lines 12 is increased in the lateral direction. As a result,it is not necessary to for the connection line to be too long in orderto realize the electrical insulation between the connection lines. Thatis, the length of the connection line (i.e., the length of theconnection line in the B direction shown in FIG. 1A) is reduced in thelongitudinal direction. Since the length (i.e., height) of theconnection line is reduced, the dimension of a non-display regionoccupied by the connection lines 12 in a longitudinal direction (i.e.the B direction as shown in FIG. 1A) can be decreased, hence decreasingthe dimension of the non-display region in the longitudinal direction,that is, reducing the size of the frame of the display panel.

As shown in FIG. 1A, in order to better realize the electricalinsulation between two adjacent lines (such as two adjacent signal lines11 or two adjacent connection lines 12) and facilitate the manufacturingof the display panel, in a process for designing the display panel, thedisplay panel is generally designed as the following structure: as forthe same type of signal lines 11, the distance between any two adjacentsignal lines 11 is identical. As for all the types of connection lines12, the distance between any two adjacent connection lines 12 isidentical. As for all the types of signal terminals, the distancebetween any two adjacent signal terminals is identical. The connectionline 12 takes a form of a folded line (i.e. the folded line enclosed bya circular region as shown in FIG. 1A).

As shown in FIG. 1A, a first region 15 is defined as a display region ofthe display panel; a second region 16 is defined as a non-display regionof the display panel, i.e. a frame. The dimension of the frame in alongitudinal direction (i.e., the direction B) is correlated with thedimension of the folded line portions 17 of all the connection lines 12in the longitudinal direction. The larger the dimension of the foldedline portion of the connection line 12 in the longitudinal direction is,the larger the dimension of the frame in the longitudinal direction is.The number of a type of signal lines may be different from the number ofthe other type of signal lines. Accordingly, the number of a type ofconnection lines may be different from the number of the other type ofconnection lines. As a result, the folded line portions of differenttypes of connection lines 12 have different dimensions in thelongitudinal direction. Since a width of a region occupied by all thesignal lines 11 is larger than a width of a driver chip 13, and acertain gap is required for all the connection lines to realize theelectrical insulation, the connection lines 12 are arranged to be bentrelative to the signal lines 11 (i.e. the connection line 12 takes aform of folded line relative to the signal line 11), so that the signallines 11 can be electrically connected to respective signal terminals 11of the driver chip 13. It should be understood that the folded lineportions of two adjacent connection lines 12 have lengths different fromeach other. FIG. 1B is a top schematic view showing the partialstructure of a display panel in which the signal terminals from a typeof signal terminals are adjacently arranged according to an embodiment.The signal terminals 14 in a structure as shown in FIG. 1A are a sametype of signal terminals. As shown in FIG. 1B, given that a verticaldistance between two adjacent signal terminals is B0; a verticaldistance between two adjacent connection lines is D0; an angle of theconnection line 12 relative to a folded line distribution of the signalline 11 is α; a height of the folded line portion of the connection line12 is H0; and the number of this type of connection lines is N, then, H0can be obtained according to the following formula: H0=(N−1)*√{squareroot over (D0 ²−B0 ²)}=(N−1)*cos a. From this formula, it can be knownthat the lengths of the folded line portions are increased as the numberof the connection lines 12 increases. As a result, the more number ofthe connection lines from the same type of connection lines 12 indicatesthe larger dimension of the folded line portions in the longitudinaldirection, i.e. the direction B. In addition, since the size of thedimension of the frame of the display panel in the longitudinaldirection is determined by the maximal value of the dimensions of thefolded line portions of all types of connection lines 12 in thelongitudinal direction, and hence the size of the dimension of the framein the longitudinal direction is determined by the dimensions of thefolded line portions of the type of the connection lines having themaximal number of connection lines in the longitudinal direction.

As shown in FIG. 1A, it is assumed that: two adjacent connection lines11 of the same type of connection lines 11 have a vertical distance C;two adjacent connection line 12 have a vertical distance D; a verticaldistance between the edge signal line 111 connected to an edgeconnection line 121 of the same type of connection lines 12 and acorresponding edge signal terminal 141 is E; the dimension of the foldedline portion of the same type of connection lines 12 in the longitudinaldirection is H. Therefore, it can be known form an geometricalrelationship that H=E*tan α=E*tan(arcsin(D/C)).

The value of H obtained by calculation is a dimension of the foldedlines portion of one type of connection lines 12 in the longitudinaldirection. It is well known from the above formula that the dimension ofthe folded line portion of each of the types of connection lines 12 inthe longitudinal direction can be obtained by calculation.

The dimension of the frame in the longitudinal direction, i.e. thedirection B, is determined by the maximal value of H, where H representsthe dimensions of the folded line portions of the all types ofconnection lines 12 in the longitudinal direction. If the dimension ofthe frame in the longitudinal direction is desired to be decreased, thevalue of H (in particularly the folded line portion of the connectionline 12 in the longitudinal direction when H is the maximal value)should be decreased.

Since the value of the vertical distance C between two adjacent signallines 11 of the same type of signal lines 11 and the value of thevertical distance D between two adjacent connection line 12 remainconstant, it can be known from the formula H=E*tan α=E*tan(arcsin(D/C)),if the dimension H of the folded line portion of the connection line 12in the longitudinal direction is decreased, the value of the verticaldistance E between the edge signal line 111 and the edge signal terminal141 should be decreased. In addition, since the arrangement of thesignal lines 11 on the display panel remains unchanged (that is, theposition of the edge signal line 111 remains unchanged), the position ofthe edge connection line 121 remains unchanged. As a result, if thevalue of the vertical distance between the edge signal line 111connected to the edge connection line 121 and the corresponding edgesignal terminal 141 is desired to be decreased, the edge signal terminal14 should be moved to the edge (the G direction as shown in FIG. 1A) ofthe driver chip (that is, decreasing the vertical distance between theedge signal terminal 14 and the edge signal line 111).

According to the display panel provided in the embodiment, in the atleast two types of signal terminals 14 provided on the driver chip, atleast a part of a first type of signal terminals and at least a part ofa second type of signal terminals are alternately and separatelyarranged such that a part of signal terminals 14 of the type of signalterminals 14 are no longer adjacent to each other. As compared with acase in the related art that the same type of signal terminals arearranged to be adjacent to each other, in the display panel provided bythe embodiments, an edge signal terminal 141 of the at least part ofdifferent types of signal terminals 14 can be moved toward to the edgeof the driver chip, so that the distance between the edge signalterminal 141 and the edge signal line 111 is decreased. The value of thedimension H of the folded line portions of the at least part ofdifferent types of connection lines 12 in the longitudinal direction isdecreased, thereby decreasing the dimension of the frame in thelongitudinal direction, that is, the dimension of the frame can bedecreased.

It should be noted that the number of the types of signal lines includedin the display panel can be any positive integer, which is larger thanor equal to 2. Since the number of the types of connection lines andsignal terminals are equal to the number of the types of the signallines, the number of the types of connection lines can be any positiveinteger, which is larger than or equal to 2, and the number of the typesof signal terminals can be any positive integer, which is larger than orequal to 2; and the number of the signal terminals arranged to be spacedapart can be any positive integer, which is larger than or equal to 2.

The structure of a display panel including two types of the signalterminals alternately and separately arranged is exemplarily illustratedas follows.

As shown in FIG. 1A, at least two types of signal lines 11 include: aplurality of first signal lines 112 and a plurality of second signallines 113; at least two types of connection lines 12 include: aplurality of first connection lines 122 and a plurality of secondconnection lines 123; at least two type of signal terminals include: aplurality of first signal terminals 142 and a plurality of second signalterminals 143.

The first signal lines 112 are electrically connected to the firstsignal terminals 142 through the first connection lines 122; the secondsignal lines 113 are electrically connected to the second signalterminals 143 through the second connection lines 123.

At least a part of the first signal terminals 142 and at least a part ofthe second signal terminals 143 are alternately and separately arranged.

It should be noted that the thick lines and the thin lines in FIG. 1Aare only illustrated to show the first signal lines 112 and the secondsignal lines 113, and the first connection liens 122 and the secondconnection lines 123. They are not intended to limit the degrees ofthickness and thinness of the signal lines 11 and connection lines 12 onthe display panel. The numbers of the first signal lines 112 and secondsignal lines 113 are only for illustration, and hence is not intended tobe limiting. A space between the first signal line 112 and the secondsignal line 113, and a space between the first connection line 122 andthe second connection line 123 are also illustrated for the description,and are not intended to be limiting.

The arrangement that at least a part of the first signal terminals 142and at least a part of the second signal terminals 143 are alternatelyand separately arranged can be achieved by any one of manners asfollows. The specific implementation of the arrangement of the signalterminals as an example is described below.

FIG. 2 is a top schematic view showing the structure of animplementation of arrangement of signal terminals of a display panelaccording to an embodiment. As shown in FIG. 2, all first signalterminals 142 are alternately arranged between second signal terminals143.

As shown in FIG. 2, all the first signal terminals 142 are arrangedbetween the plurality of second signal terminals 143, and the edgesignal terminals belongs to the second signal terminals 143. In sucharrangement, the number of the first signal terminals 142 is less thanthat of the second signal terminals 143. That is, in the arrangementprovided in FIG. 2, all the type of signal terminals (i.e. all the firstsignal terminals 142) having a smaller number of signal terminals arearranged between the type of signal terminals having a larger number ofsignal terminals (i.e. the second signal terminals 143).

According to the arrangement of the signal terminals provided in FIG. 2,it is possible to move the edge signal terminals of the type of signalterminals having the larger number of signal terminals towards an edgeof the driver chip 13, so that a vertical distance (i.e. the letter E asshown in FIG. 1A) between the edge signal terminal of the type of signalterminals having the larger number of signal terminals and an edgesignal line connected to the edge signal terminal can be decreased, andhence the dimension of a non-display region occupied by the connectionlines corresponding to the type of signal terminals having the largernumber of signal terminals can be decreased in the longitudinaldirection. Since the dimension of the frame in the longitudinaldirection is determined by the dimension of the non-display-regionoccupied by the connection lines corresponding to the type of signalterminals having the maximal number of signal terminals in thelongitudinal direction, in the implementation of the arrangement of thesignal terminals provided in FIG. 2, the size of the frame can decreasedin the longitudinal direction.

It should be noted that the number of the first signal terminals 142located between two adjacent second signal terminals 143 can be anypositive integer, for example, as shown by the numerical reference 201in FIG. 2, the number of the first signal terminal 142 between twosecond signal terminals 143 is 1; as shown by the numerical reference202 in FIG. 2, the number of the first signal terminals 142 between twosecond signal terminals 143 is 2. The number of the second signalterminal 143 between two adjacent first signal terminals 142 can be anypositive integer, for example, as shown by the numerical reference 203in FIG. 2, the number of the second signal terminal 143 between twofirst signal terminals 142 is 1; as shown by the numerical reference 204in FIG. 2, the number of the second signal terminals 143 between twofirst signal terminals 142 is 2.

FIG. 3 is a top schematic view showing the structure of anotherimplementation of arrangement of terminals of a display panel accordingto an embodiment. As shown in FIG. 3, every two of the first signalterminals 142 are spaced from each other by one of the second signalterminals 143.

As shown in FIG. 3, every two of the first signal terminals 142 arespaced from each other by one of the adjacent second signal terminals143, so that any two adjacent first signal terminals 142 is providedwith one second signal terminal 143 therebetween. In such anarrangement, the number of the first signal terminals 142 is less thanthat of the second signal terminals 143. That is, in the arrangement ofthe signal terminals provided in FIG. 3, every two of the signalterminals from the type of signal terminals having a smaller number ofsignal terminals (i.e. the first signal terminals 142) are spaced fromeach other by one of the type of signal terminals having a larger numberof signal terminals (i.e. the signal terminals 143).

In the arrangement of the signal terminals provided in FIG. 3, the edgesignal terminal from the type of signal terminals having a larger numberof signal terminals can be moved towards the edge of the driver chip 13,so that a vertical distance between the edge signal terminal of the typeof signal terminals having a larger number of signal terminals and anedge signal line connected to the edge signal terminal, i.e. thedistance E as shown in FIG. 1A, can be decreased, and further thedimension of a non-display region occupied by the connection linescorresponding to the type of signal terminals having the larger numberof signal terminals can be decreased in the longitudinal direction.Since the dimension of the frame in the longitudinal direction isdetermined by the dimension of the non-display region occupied by theconnection lines corresponding to the type of signal terminals havingthe maximal number of signal terminals in the longitudinal direction,the dimension of the frame in the longitudinal direction can bedecreased according to the implementation of the arrangement of thesignal terminals provided in FIG. 3. In addition, every two of the firstsignal terminals 142 are spaced from each other by one of the secondsignal terminals 143 such that a distance between the first signalterminals 142 is enlarged, as a result, when the signal lines areelectrically connected to first signal terminals 142 through theconnection lines, the space between the connection lines is alsoenlarged, thereby simplifying the manufacturing process of the displaypanel.

It should be noted that every two of the first signal terminals 142 canbe spaced from each other by any of the second signal terminals 143,that is, the first signal terminals 142 can be located at any region.

FIG. 4 is a top schematic view showing the structure of anotherimplementation of arrangement of signal terminals of a display panelaccording to an embodiment. As shown in FIG. 4, any two of the firstsignal terminals 142 are spaced from each other by a part of secondsignal terminals 143, wherein in each of the both sides of the driverchip 13, a part of the first signal terminals 142 and a part of thesecond signal terminals 143 are alternately arranged separately, and inthe middle of the driver chip 13, a part of the second signal terminalsare arranged.

As shown in FIG. 4, any two of the first signal terminals 142 are spacedfrom each other by a part of second signal terminals 143, wherein ineach of the both sides of the driver chip 13, a part of the first signalterminals 142 and a part of the second signal terminals 143 arealternately arranged separately, and in the middle of the driver chip13, a part of the second signal terminals are arranged. In such anarrangement, the number of the first signal terminals 142 is less thanthat of the second signal terminals 143, that is, in the arrangement ofthe signal terminals provided in FIG. 4, a smaller number of signalterminals are arranged separately by a larger number of signalterminals, and all the smaller number of signal terminals 142 and thelarger number of signal terminals 143 from both ends of all the secondsignal terminals 143 are alternately and separately arranged.

In the arrangement of the signal terminals provided in FIG. 4, the edgesignal terminal from the type of signal terminals having a larger numberof signal terminals can be moved towards the edge of the driver chip 13,so that a vertical distance between the edge signal terminal of the typeof signal terminals having a larger number of signal terminals and anedge signal line connected to the edge signal terminal, i.e. thedistance E as shown in FIG. 1A, can be decreased, and further thedimension of a non-display region occupied by the connection linescorresponding to the type of signal terminals having the larger numberof signal terminals can be decreased in the longitudinal direction.Since the dimension of the frame in the longitudinal direction isdetermined by the dimension of the non-display region occupied by theconnection lines corresponding to the type of signal terminals havingthe maximal number of signal terminals in the longitudinal direction,the dimension of the frame in the longitudinal direction can bedecreased according to the implementation of the arrangement of thesignal terminals provided in FIG. 4. In addition, every two of the firstsignal terminals 142 are spaced from each other by one of the secondsignal terminals 143 such that a distance between the first signalterminals 142 is enlarged. As a result, when the signal lines areelectrically connected to first signal terminals 142 through theconnection lines, the space between the connection lines is alsoenlarged, thereby simplifying the manufacturing process of the displaypanel. In addition, as compared with the embodiment as shown in FIG. 3,in the present embodiment of FIG. 4, any two of the first signalterminals 142 are spaced from each other by a part of second signalterminals 143, wherein in each of the both sides of the driver chip 13,a part of the first signal terminals 142 and a part of the second signalterminals 143 are alternately arranged separately, and in the middle ofthe driver chip 13, a part of the second signal terminals are arranged.When the signal lines are electrically connected to the first signalterminals 142 through the connection lines, only a half number ofconnection lines rather than all the connection lines are adjacent toeach other (since a half number of first signal terminal are located ateach of both ends of all the first signal terminals 142, the half numberof signal terminals are adjacent to each other, and hence, the halfnumber of connection lines are adjacent to each other). Therefore, thenumber of connection lines adjacent to each other is decreased, therebysimplifying the manufacturing process of the display panel.

FIG. 5 is a top schematic view showing the structure of anotherimplementation of arrangement of signal terminals of a display panelaccording to an embodiment. As shown in FIG. 5, all the first signalterminals 142 are evenly arranged between all of the second signalterminals 143.

As shown in FIG. 5, all the first signal terminals 142 are evenlyarranged between all of the second signal terminals 143 such that thenumbers of the second signal terminals 143 provided between every twoadjacent first signal terminals 142 are identical. In such anarrangement, the number of the first signal terminals 142 is less thanthat of all the second signal terminals 143, that is, the distributionof signal terminals provided in FIG. 5 is that all the first signalterminals 142 having a relatively small number of signal terminals areevenly arranged between the second signal terminals 143 having arelatively large number of signal terminals.

In the arrangement of the signal terminals provided in FIG. 5, the edgesignal terminal from the type of signal terminals having a larger numberof signal terminals can be moved towards the edge of the driver chip 13,so that a vertical distance between the edge signal terminal of the typeof signal terminals having a larger number of signal terminals and anedge signal line connected to the edge signal terminal, i.e. thedistance E as shown in FIG. 1A, can be decreased, and further thedimension of a non-display region occupied by the connection linescorresponding to the type of signal terminals having the larger numberof signal terminals can be decreased in the longitudinal direction.Since the dimension of the frame in the longitudinal direction isdetermined by the dimension of the non-display region occupied by theconnection lines corresponding to the type of signal terminals havingthe maximal number of signal terminals in the longitudinal direction,the dimension of the frame in the longitudinal direction can bedecreased according to the implementation of the arrangement of thesignal terminals provided in FIG. 5. In addition, as compared with theabove embodiments, the advantage of the present embodiment lies in thatthe first signal terminals 142 are evenly arranged between all of thesecond signal terminals 143 such that a distance between the secondsignal terminals 143 is maximized. When the signal line are electricallyconnected to first signal terminals 142 and second signal terminals 143,the connection lines corresponding to every two adjacent first signalterminals 142 have a relative large distance therebetween, and theconnection lines corresponding to every two adjacent second signalterminals 143 also have a relative larger distance therebetween, therebysimplifying the manufacturing process of the display panel.

FIG. 6 is a top schematic view showing the structure of anotherimplementation of arrangement of signal terminals of a display panelaccording to an embodiment. As shown in FIG. 6, in at least two types ofsignal terminals, the signal terminals 601 of the same type of signalterminals having a maximal number of signal terminals are located atboth ends of a driver chip.

As shown in FIG. 6, in at least two types of signal terminals, thesignal terminals 601 from the type of signal terminals having a maximalnumber of signal terminals are located at both ends of the driver chip13, other signal terminals are arranged in the middle region of thedriver chip 13. According to the distribution manner of the signalterminals provided in FIG. 6, an edge signal terminal of the type ofsignal terminals having a maximal number of signal terminals can movetowards an edge of the driver chip 13. Hence, the dimension of anon-display region occupied by the connection lines corresponding to thetype of signal terminals having the maximal number of signal terminalscan be decreased in the longitudinal direction. Since the dimension ofthe frame in the longitudinal direction is determined by the dimensionof the non-display region occupied by the connection lines correspondingto the same type of signal terminals having the maximal number of signalterminals in the longitudinal direction, the dimension of the frame inthe longitudinal direction can be reduced according to theimplementation of the distribution of the signal terminals provided inFIG. 6.

It should be noted that the number of signal terminals can be anyinteger equal to or larger than 2. FIG. 6 only shows a case in which twotypes of signal terminals are provided.
